< p > The TQPalette class contains color groups for each widget state.
< p >
< p > A palette consists of three color groups: < em > active< / em > , < em > disabled< / em > ,
and < em > inactive< / em > . All widgets contain a palette, and all widgets in
TQt use their palette to draw themselves. This makes the user
interface easily configurable and easier to keep consistent.
< p > If you create a new widget we strongly recommend that you use the
colors in the palette rather than hard-coding specific colors.
< p > The color groups:
< ul >
< li > The < a href = "#active" > active< / a > () group is used for the window that has < a href = "focus.html#keyboard-focus" > keyboard focus< / a > .
< li > The < a href = "#inactive" > inactive< / a > () group is used for other windows.
< li > The < a href = "#disabled" > disabled< / a > () group is used for widgets (not windows) that are
disabled for some reason.
< / ul >
< p > Both active and inactive windows can contain disabled widgets.
(Disabled widgets are often called < em > inaccessible< / em > or < em > grayed out< / em > .)
< p > In < a href = "motif-extension.html#Motif" > Motif< / a > style, active() and inactive() look the same. In Windows
2000 style and Macintosh Platinum style, the two styles look
slightly different.
< p > There are < a href = "#setActive" > setActive< / a > (), < a href = "#setInactive" > setInactive< / a > (), and < a href = "#setDisabled" > setDisabled< / a > () functions
to modify the palette.
< p > Colors and brushes can be set for particular roles in any of a
palette's color groups with < a href = "#setColor" > setColor< / a > () and < a href = "#setBrush" > setBrush< / a > ().
< p > You can copy a palette using the copy constructor and test to see
if two palettes are < em > identical< / em > using < a href = "#isCopyOf" > isCopyOf< / a > ().

colors.

< / h3 > < b > This function is obsolete.< / b > It is provided to keep old source working. We strongly advise against using it in new code.
< p > Constructs a palette from the < em > button< / em > color. The other colors are
automatically calculated, based on this color. Background will be
the button color as well.

< / h3 >
Returns a < a href = "shclass.html#deep-copy" > deep copy< / a > of this palette.
< p > < b > Warning:< / b > This is slower than the copy constructor and assignment
operator and offers no benefits.
< h3 class = fn > const < a href = "qcolorgroup.html" > TQColorGroup< / a > & < a name = "disabled" > < / a > TQPalette::disabled () const
< / h3 >
< p > Returns the disabled color group of this palette.

< h3 class = fn > bool < a name = "isCopyOf" > < / a > TQPalette::isCopyOf ( const < a href = "ntqpalette.html" > TQPalette< / a > & p )
< / h3 >
Returns TRUE if this palette and < em > p< / em > are copies of each other,
i.e. one of them was created as a copy of the other and neither
was subsequently modified; otherwise returns FALSE. This is much
stricter than equality.
< p > < p > See also < a href = "#operator-eq" > operator=< / a > () and < a href = "#operator-eq-eq" > operator==< / a > ().

Assigns < em > p< / em > to this palette and returns a reference to this
palette.
< p > This is fast (it uses copy-on-write).

otherwise returns FALSE (slowly).
< h3 class = fn > int < a name = "serialNumber" > < / a > TQPalette::serialNumber () const
< / h3 >
< p > Returns a number that uniquely identifies this TQPalette object.
The serial number is intended for caching. Its value may not be
used for anything other than equality testing.
< p > Note that TQPalette uses copy-on-write, and the serial number
changes during the lazy copy operation (detach()), not during a
< a href = "shclass.html#shallow-copy" > shallow copy< / a > (copy constructor or assignment).
